“You look at the questions; Donald Trump, are you a comic book villan? Ben Carson, can you do math? John Kaisch, can you insult those two people over here. Marco Rubio, will you resign? Jeb Bush, why have your numbers fallen? How about talking about the substantive issues people care about?” Cruz asked, almost being drowned out as the audience in Boulder, Colo., loudly voiced its approval.

Cruz has been edging up in the poll ratings of late, now fifth in the national averages according to RealClearPolitics and fourth in early-voting Iowa. He is positioned as a potential conservative standard-bearer should Trump and Carson, the current front-runners, falter.

The Texas senator contrasted CNBC's questions with the ones posed to Democrats during their debate last week, where he said "every fawning question" was about which of the candidates was "more handsome and wise."

"The men and women on this stage have more ideas, more experience, more common sense than every participant in the Democratic debate. That debate reflected a debate between the Bolsheviks and the Mensheviks."

Attacks on the media often benefit Republican candidates, as former Speaker Newt Gingrich (Ga.) and former Sen. Rick Santorum (Pa.) proved in the 2012 race.

Cruz’s remarks appeared to score big with the audience beyond the hall as well.

Republican pollster Frank Luntz, who is running a focus group of debate-watchers, said that the comments caused the dials measuring approval to hit 98. “That’s the highest score we’ve ever measured. EVER,” Luntz tweeted.

The Texas senator’s remarks also found sympathy in a more unlikely quarter. Left-leaning TV talk show host Bill Maher tweeted: “oh my god did i just hear Ted Cruz say something awesome that i agree with? Yes. The media is even stupider than the pols.”
